INTRAMEDULLARY RODDING IN TYPE-III OSTEOGENESIS IMPERFECTA - EFFECTS ON NEUROMOTOR DEVELOPMENT IN 10 CHILDREN

We studied retrospectively gross motor development and the impact of i ntramedullary redding in 10 children with type III osteogenesis imperf ecta (OI). There was a pronounced delay in motor development and the o rder in achieving gross motor milestones differed from the normal deve lopmental sequence. Static milestones developed at an earlier stage th an dynamic milestones. Intramedullary redding of the lower extremities prior to the age of 3.5 years enhanced neuromotor development, especi ally regarding the milestones supported standing, rolling from prone t o supine and crawling with abdomen on the floor. The different sequenc e in achieving gross motor milestones should have implications for fut ure rehabilitation programs and for orthopedic surgery.
